Magnitude 6.4 quake jolts Indonesia's Lombok island -USGS
The quake may have also impacted Mount Rinjani national park, a popular trekking destination.
The quake, which was quickly followed by an aftershock of magnitude 5.4 in the same area, was centred in the northern part of the island, 30.7 miles (49.5 km) northeast of the city of Mataram, the U.S. Geological Survey (USGS) said.
Sutopo Purwo Nugroho, the agency spokesman, posted on Twitter pictures of houses with collapsed roofs and walls.
"Rinjani mountain climbing is closed temporarily because there is an indication of landslide around the mountain," Nugroho, said in a statement.
Local news Metro TV reported that people were still sleeping when the first quake hit and they quickly fled their houses in panic. Most of the people were still waiting outside their houses in fear of aftershocks, Metro TV said.
The earthquake struck at 6:47 a.m. on Sunday (2247 GMT on Saturday) and was only 4.35 miles deep (7 km), a shallow depth that would have amplified its effect. The second struck less than an hour later
A magnitude 6.4 earthquake is considered strong and is capable of causing severe damage.
The European-Mediterranean Seismological Centre (EMSC), the European quake agency, put the magnitude at 6.5.
The earthquake was on land and did not trigger any waves or tsunami.
Lombok is the next island east of Bali.
Quakes are common in Indonesia, which is located on the seismically active "Ring of Fire" that surrounds the shores of the Pacific Ocean.
